WINDOW-SASH.

T all whom t may concern Be it known that I, BEDFORD KATUSKY, a citizenof the United States, residing in the county of Jackson, State ofMinnesota, have invented certain new and useful Improvements inVindow-Sashes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in window sashes, and my object isto improve the construction and increase the utility of devices of thischaracter.

A further object is to provide a form of sash frame which may beextended into a straight line by means of pivot points located at theintersection of the frame members.

A further object is to provide a form of sash frame in which the glassis secured by the frame itself, thus eliminating the additional securingmeans now used for this purpose.

At further object is to provide a weatherproof joint between the glassand frame.

lt will also be understood that a primary object which governs to someextent every other consideration is to reduce the cost of the device tothe lowest limit possible consistent with efficiency, sightliness anddurability.

`With the above and other objects in view the invention consistsprimarily of a plurality of rectilinear frame members having glassretaining grooves in one face thereof, mortised joints between saidmembers, means whereby said joints will permit angular movement of saidmembers, and means for locking the frame in a closed position.

The invention further consists in a cer* tain construction, combinationand arrangement of parts and details as is hereinafter more fullydescribed, particularly pointed out in the appended claim, andillustrated in the accompanying' drawings, which show a preferredembodiment of the invention.

Referring to these drawings which are attached to and form a part ofthis applica tion, Figure l is an elevation of my improved window sashshowing the glass in place therein. Fig. 2 is a side elevation of thesash-frame in the extended position, Fig. 8 is a sectional view on theline 3 3 of Fig. 2, Fig. 4 is a sectional view on the line 4 4 of F 2,Fig. 5 is a detail view Specification of Letters Patent.

of the pivot screw used in my mortise joint,

F ig. G is a side view of a corner joint when nate corresponding partsthroughout, l in-l dicates the top transverse member of the" sash frameand 2 the bottom transverse member; the two being identical inconstruction the description of one will be understood to apply to theother. The member l comprises a body section, here designated 2', ofapproximately rectangular section as shown in Fig. il, on the ends ofsaid body section the material being reduced as shown at 5 to formtenons 6, said tenons terminating in arcuate portions 7. At t-hejuncture of the tenons with the body portion a squared shoulder 9 isformed, the purpose of said shoulder being as will hereinafter appear.

Referring to the longitudinal frame members by the numeral 8 it will beseen from Fig. 4 that these members are of a section identical with thatofthe transverse member and are provided at the extremities withbifurcated portions lO between the confronting' inner faces of which thetenons 6 are pivoted.

Referring to the sectional View of Fig. 3 it will be seen that thebefore mentioned bifurcation is not complete, the lower or outer facesof the members 8 being left uncut as shown at l2. rl`he inner faces ofthe bifurcated ends are squared as shown at 13 while the outward cornersof said ends are cut arcuately as shown at lei.

Referring again to the sectional view of Fig. 4l it will be seen thatbetween the inner faces of the frame members a central groove l5 isformed, and it is preferable that this groove should be slightlyundercut. Along the bottom of the groove is laid a strip of packingmaterial, preferably weather-proof felt. In order to assemble the frameabove described, transverse bores here designated 16 are formed in thebifurcated end portions of the longitudinal members and in the tenons ofthe transverse members. Fitting said members together as shown in F ig.2, they are pivotally secured by means of the fastening screws or pivotscrews here designated as 17 and shown in Fig. 5. lt will be seen thatthese screws have an outer plain cylindrical portion, an upper' taperingportion, and a slotted head formed integrally ratentea aaiye, isis.

with the upper taper portion. rI`he diameter of the cylindrical portionis approximately equal to thatV of the bores in the frame members, itwill be seen that on entering said screw into the bores that the taperedportion may be engaged in the outer bifurcated sections thus providing asecuring means for the cylindrical pivot or bearing portion.

'I`o secure the glass in the frame, the latter is extended in theposition shown in Fig. 2 and one edge of the glass then introduced lintothe groove of one of the frame members. rIhe adjacent member is thenpivoted on the bearing screw before described until the shoulders 9contact with the squared inner faces of the longitudinal members, at thesame time the inner face of the tenon contacting with the rear wall ofthe recess formed by the bifurcated portions. It will be seen that whenthe members are in rectangular relation as shown inl locked against Fig.1 they are positively angular movement inwardly. After the frame membershave been closed in the position shown 1n Fig. 1 the final fastening 1seected by means of a pivot screw passing through the registering boresof tenon and mortise, as described above.

It will be seen from the above description that I have provided a formof extensible or knock-down sash which may be opened or extended into anapproximately straight line and which may thus be packed in quantitiesfor shipment without wasting space. It will further be seen that toassemble this sash no tools, except possibly a screw driver is needed,and that putty, molding and such fastenings as have been applied in thepast are not necessary in order to secure the present sash about itsglass. It will further be observed that when so secured the frame isabsolutely rigid, and that the resilient packing material in the bottomof the glass retaining grooves forms a weather-proof joint.

The improved sash may be made in any desired form or size and of anydesired material, although as described it is conventional in shape andmade of wood.

That I claim is;

A window sash, comprising side members, a top member, and a bottommember, each of said members being provided with a longitudinallyextending glass receiving groove, the sides of said groove diverginginwardly whereby the base of the groove is wider than the openingthereto, and packing strips seated in the bases of said grooves.

In testimony whereof, I affix my signature, in presence of twowitnesses.
